Yesterday I ran out of inodes while untarring something, and after
clearing out a lot of temporary files, I noticed something fishy: the
number of files found by find and the number of used inodes reported
by df differ by a couple orders of magnitude on /home [1]:

# df -i /home
Filesystem            Inodes   IUsed   IFree IUse% Mounted on
/dev/wd0j            12671998 12542780  129218   99% /home
# pwd
# find . -xdev -ls | awk ' { print $1 } ' | sort -n | uniq | wc -l

I'm running NetBSD 2.0.2, and /home is normally mounted softdep,
nodev, noatime.

That's the problem.  Here's a possible explanation, but I'm not sure
if this is the cause: last week, after a crash, fsck on my /home file
system printed this message for at least a few thousand integers <N>:


After it finished, by investigation, no files seemed to have been
lost, and I didn't have time to do look into it.  Now I can't find the
meaning of this message documented anyplace, and the code in
src/sbin/fsck_ffs/pass5.c where this message seems to originate
doesn't mean much to me.

Anyhow, can I do anything other than dump, recreate, and undump the
file system to get the inodes back?

Thank you,

[1] Counting files this way for other file systems and comparing to
`df -i` gives these results:
